Rear End Swap

Been having some trouble locating a rear differential for my truck. My differential has the 3.42 gears with the g80 locker. Ring and pinion gears are shredded, but the locker looks okay. I have found plenty of rear ends with just the 3.42 gears but no locker. Would it be that difficult to just get a rear differential without the locker and install my locker in it?
